Ball Mill Design/Power Calculation
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or The following equation is used to determine the power that wet grinding overflow ball mills should draw For mills larger than 33 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill This is called the ball size factor S Rod and Ball Mills by CA Rowland and DM Kjos @ AllisChalmersBall Mill Motor Power Draw Sizing and Design FormulaDec 12, 2016 The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed Ball Mill Design/Power Calculation LinkedIn
